QUICK-ACTING- VISE.

Application filed December 16, 1915.

To all whom it may concern Be it known that 1, Arrow A. MoKnN /an, acitizen of the United States, and resident of Cambridge, in the countyof Middlesex and State of Massachusetts, have invented a new and usefulImprovement in Quick- Acting Vises, of which the following is aspecification, reference being had to the accompanying drawings.

This invention has for its object to provide a vise having onestationary and one movable jaw, the latter jaw being adapted to bequickly closed and opened and se curely locked with said vise whenclosed, said movable jaw being preferably adapted to be used with thetype of folding vise shown in my patent issued August 31, 1915, andnumbered 1,157,959, on a portable hand vise, and being specially adaptedfor the use of carpenters and other mechanics.

The invention consists in the improvements whichI will now proceed todescribe and claim.

represents a sectional view taken on linen 12-12 in Fig. 8, looking inthe direction of the arrows, showing the movable jaw closed upon a pieceof material. Fig. 13, represents the same view as Fig. 12, but shows themovable'jaw open with the material freed therefrom. Fig. 14:, representsa perspective view showing a modified construction for the frame member,the bottom edge of which is provided with teeth, or other serrations orroughening, as against the plain surface shown in the other views of thedrawing, for affording the locking jaws of the anchoring member a meansfor preventing slipping along the frame of the vise when the jaw is inlocked position therewith. Fig. 15, represents a perspective view of oneof the ends of the locking hanger member shown in Fig. 11, which mayalso be provided with teeth, or other such serrations or roughening, forengaging either with the plain frame edge shown in the drawings, or withthe type of locking edge shown in Fig. 14.

The same reference numbers indicate the same or similar parts in all theviews, and the term movable aw refers to the entire mechanism of theworking jaw of the vise as a unit.

The numeral 1, in its entirety, represents a rigid frame member which ispreferably provided with a stationary jaw 2 on one end and the parallelruns 3 and 4: upon which the movable jaw member rides, which runs 3 and1 are provided with the top surfaces 5 and 6, the lower surfaces 7 and 8and the inner guide surfaces 9 and 10, respectively. The movable jaw ofthe vise consists of the supporting guide plate 11 which has the sideguide-runs 12 and 13, and isadapted to rest upon the top surfaces 5 and6 between the sides 9 and 10 of the runs 3 and 4:. The guide-plate l1isalso provided with the supporting lugs 14 and 15 which projectupwardly from the plate and are provided with the transverse'drilledholes 16 and 17, within which is supported the supporting-shaft 18,which shaft is preferably provided with the cotter-pins 19 for holdingthe same secured in set position. The guideplate 11 is also provided onthe side 20 with the web 21 having the boss 22 which has the tapped hole23 within which is secured the adjustable tension-springstud 24 whichholds the tension spring 25 in working po- 7 and ,8, of the runs 3 theopening 26 in the top of the same be: tWeen the lugs 14 and 15, as shownin Fig. 10.

27 is the floating hanger locking member which is provided with theelongated hole 28 for fioatably fitting over the supporting shaft '18,the head 29, and the locking j aws- 30 and 31 which engage with theundersides and 4, respectively. 32 is the anchoring lever which isprovided with the forked and cam-shaped hub member 33 which is providedwith the hole 34 for pivotally fitting on the shaft 18.

35 is the movable-jaw-plate operating lever which is also provided withthe cam shaped hub 35 and the hole35 for pivotally fitting on thesupporting-shaft 18.

7 roughened surface for engaging with the.

36 is the movable-jaw-plate which has the working side 37 and isprovided on the rear side 38 with the cam engaging lug 39 and the sidesupports 40 and 41 which engage on their bottom surfaces with the topsurfaces 5 and 6 of the runs 3 and 4, respectively, and betweenwhichside supports the guide-plate 11 sets. The 'movable-jaw-plate 36 is alsoprovided on the bottom of the same with the guide members 42 and 43, forengaging with the undersides of the runs 3 and 4, respectively, as shownin Fig.8.

44 represents a piece of material shown supported in the vise.

45 is a modified type of run which may be used for the frame member ofthe vise,

which run'is provided with the underside 46' for the guide member 42 ofthe movable jaw-plate 36 to engage with.

47 is a toothed, knurled, or otherwise locking-jaws 30 and 31 of thelocking hanger member 27.

48 is a modified type of locking-jaw for the locking hanger member 27,and is provided with the rough or toothed surface 49,

for engaging with the surface 47 shown in Fig. 14, for overcoming anytendency of slipping on the part, of the anchoring member when the samehas once been locked in the anchoring position.

Having thus described the parts of my invention in detail, the manner inwhich the same is assembled and operated is as follows: Themovable-jaw-plate 36 is first set upon the runs of the viseby being positioned diagonally across the same, which permits the guiding-lugs 42 and43 to engage with the surfaces 7 and 8 of the runs of the vise as themovable-jaw-plate 36' is brought into the parallel position with thestationary jaw 2 of the vise. With the supporting-shaft 18 removed fromthe guideplate 11, the plate is set into engaging posivtion with theruns of the vise, as shown in Fig. 1. The fioatinglocking member 27 isthen associated with the guide-plate 11 and the runs of the vlsebyinsertingthe head member 29 through the opening 26 of the V guide-plate11 form the underside thereof.

The forked-anchoring-lever 32 is then engaged with. the floating lockingmember 27, as shown in Figs. 7 and 9, the hub of said lever 32 being setadjacent to the supporting-lug 16 of the guide-plate 11 with the hole 34in line with the hole 16 in the supporting-lug 14. Themovable-jawplate-operating-lever is then set adjacent to said forkedlever, with the hole 37 in line with the hole 34 of the forked lever.The supporting-shaft 18 is then inserted through V the holes in thesupporting-lugs 14 and 15,

the hole 34 of the forked lever, the hole 28 of the hanger lockingmember 27 and the hole 35 of the movable-j aw-plate operating lever 35for supporting said levers and said hanger member in operating positionwith said guide-plate. The supporting-shaft 18 is then preferably pinnedin position by means of the cotter-pins 19 on the ends of the same. Thetension coupling spring 25 is then set to engage with themovable-jawplate 36, as shown in Fig. 8, and is supported intosetengaging position by means of the tension sprlng supporting and adusting-stud 24 which is adjustably secured, as

shown in Figs. 10, 12 and 13, to theguideplate 11, by being'screwed inthe hole 23 which is specially provided therefor. It may be observedthat the tension between the spring which engages the clampingmovable-jaw-plate 36 with the anchoring member ofthe vise, may be variedto suit accordi ing as may be desired,-sufiicient clearance between thespring and the boss 22, as shown in Fig. 10, being always required forpermitting the play necessary between the anchoring member of the viseand the clamping and working jaw of the same. It may be observed thatthe cam member 35 of the movable-jaw-plate operating lever '35 en- Toslide the movable jaw'to any part of the vise, the same may beaccomplished by raising the levers 32 and 35 into their upwardpositions, as shown in Figs. 1 and 2, which permits thelocking jaws 30.and 31 of the hanger locking member 27 to drop downward andsufficiently'away from the surfaces 7-and-8of the runs3 and4,respectively, to

lot

' gages with the cam-lug 39 of the movable- 9 jaw-plate 36, as shown inFigs. 7 and 12.110

permit the same toclear said runs, thus;

leaving the anchoring member of the vise free to sllde along the runs ofthe same. To

engage the movable-jaw-plate for clamping a piece of material 44in thevise, the movablejaw member is preferably brought near to, but notengaging with, thematerial, as shown in Fig. 13, when the anchoringlever 32 may be lowered into the locking position, which lever, byvirtue of the action of the cam-shaped hubs33 engaging with the heads 29of the hanger locking member 27, raises the hanger locking member 27,and consequently brings the locking-jaws 30 and 31 of the same intogripping contact with the lower surfaces 7 and 8 of the runs 3 and l,respectively, thereby gripping and loclr ing the anchoring membertherewith. The movableplate-jaw operating lever 35 may then be lowered,as shown in Fig. 12, which results in bringing the cam 35 into workingcontact with the camlug 39 of the movablejaw-plate 36, and thus forcesthe same against the tension of the coupling spring 25 to engage withthe material M, and grips and clamps the same between the stationary jaw2 and the movable jaw of the vise; thus closing the working jaw of thevise on the material, as shown in Fig. 12. To open the jaw for releasingthe material, the lever 35 is swung in the upward position, as shown inFig. 13, which allows the movable-jawplate 36 to automatically freeitself from the material by the action of the coupling spring forcingthe movable-jaw-plate back to the original position with the anchoringmember. The material is thus freed between the jaws of the vise and maythen be removed from the same.

It may be observed that the anchoring member of the vise may be lockedwith the runs of the same by, applying the proper pressure to the lever32 downward, which brings the cam section of the same into workingengagement with the supporting head 29 of the locking plate, and thefarther the lever 32 is forced downward, the greater is the action ofthe cam and the greater is the gripping power between the locking jaws30 and 31 and the guide-plate 11 upon the runs 3 and a between them,-theincline of the cam 33. increasing as the lever is ad vanced in thedownward position. It may also be observed that as the movable-jawplateoperating lever 35 is advanced in the lower position, that the inclineof the cam member increases, and thus allows the proper grippingpressure on the movablejaw-plate 36 necessary for holding the materialin clamped position between the jaws of the vise. Thus it must beunderstood that the design and construction of the combination of thefloating working jaw and the anchoring member of the movable jaw of thevise permits of the application of extra gripping power after theanchoring member has been locked into position with the frame of thevise, and also furnishes a quick acting vise, in that the operation ofthe same is very simple and effective, the movable jaw permitting ofopening and closing rapidly and positioning readily in working relation,or otherwise on the vise.

It may be understood that where the vise is to be used by an operatorfor the handling of standard sizes of articles or material, that by oncesetting the anchoring member of the vise in proper relationship with theparticular dimensions of the article or material, that the operator mayconfine himself to the manipulation of the movable-jaw-plate operatinglever 35, as shown in Figs. 12- and 13, without resetting the anchoringmember. it may further be observed that the construction of the movablejaw permits of a powerful gripping feature which may be applied to thearticle or material held in the vise according as may be required by theoperator. It may also be observed that by raising the movable-jimplateoperating lever into the upward position, where no great pressure isrequired to grip the material held in the vise, that by simply forcingthe guide member 11 as far as it will go, toward the material to begripped, and locking the anchoring member by lowering the anchoringlever 32, that the material will be suiliciently gripped for ordinarypurposes between the jaws of the vise, since, as shown in Fig. 13, themovablejaw-plate 36, when in the normal position with the operatinglever upward, sets ad jacent to the guide member 11; so that it willappear that it is not always necessary to manipulate themovable-jaw-plate operating lever 35 for completing the grippingoperation of the movable jaw of the vise.

It may be understood that a vise, such as I have'herein disclosed, is avery useful apparatus for carpenters, especially more particularly foruse in their finishing work, and where it is required to provide greatergripping force upon the material held in the vise, the modified grippingruns, shown in Fig. 14, and the modified gripping jaw shown in Fig. 15,may be used to advantage for positivelv preventing slipping on the partof the anchoring member when the same has once become locked in theworking position and further pressure is'applied to the floating jaw ofthe vise by the manipulation of the movable-jaw-plate operating lever35, in the downward direction.

While the preferred embodiments of my invention have been described indetail, it will be understood that I do not wish to be limited to theparticular construction set forth, since various changes in the form,material, proportions, and arrangement of parts and in the details ofconstruction may be resorted to without departing from the spirit andscope of the invention, or forfeiting any of the advantages contained inthe same, heretofore described, and defined in the subjoined claims.
